Abstract
Propagation effects in the high-order harmonic generation of high-inte nsity subpicosecond KrF laser radiation (6 x 10(15) W/cm(2)) in carbon vapor and low charged carbon plasma are studied. An anomalous behavio ur of the fifth harmonic is observed. The continuous growth of its int ensity with the plasma length is explained by defocusing of laser radi ation and noncollinear phase-matched difference-frequency mixing.
